Understanding of how best to treat inflammatory bowel disease (IBD) has evolved over the last ten years. Evidence now suggests that the most effective therapy early in the course of Crohn's disease (CD) and ulcerative colitis (UC) involves the use of immune suppressing medications such as the anti-Tumor Necrosis Factor (anti-TNF) agents infliximab, adalimumab, and certolizumab. However, many CD and UC patients still ultimately require surgery despite the use of these medications. Side effects of the anti-TNF agents include increased risk of infections due to their effect on the immune system. Little is known about how use of these medications ...
